The set {1, pi, -3.9} is one such set.
4 belongs to any set that contains it. So {1, pi, 4, -37.5689, sqrt(2)} is a possible answer.
It is a set containing the single number, 3.14, a rational number. This must not be confused with the number pi, which is approximately 3.14 but is an irrational number.
Neative and it's a whole number, I think
It belongs to the interval (25, 27.3), or [-20.9, 10*pi], and infinitely more such intervals.It also belongs to the set of rational numbers, real numbers, complex numbers and quaternions.
Pi is both an irrational number and a transcendental number.
pi is a single number , not a set. Since it is not a set, it cannot have a subset.
No, pi is a set number.
If you're talking about real numbers, then it is an irrational number. Any number that cannot be written as a fraction is irrational. You cannot write pi as a fraction (22/7 is just an estimate). So any thing multiplied with pi cannot be rational either.
The set {1, pi, -3.9} is one such set.
Pi is an Irrational number, which is one of the two subcategories of real numbers.
what set is 0.56
It belongs to any subset which contains it. For example,the interval (3, 4){pi}{1, pi, 3/7}{27, sqrt(7), pi}
It belongs to any set which contains it. For example: {-21} {pi, yellow, -21, Germany} {numbers smaller than -17}
4 belongs to any set that contains it. So {1, pi, 4, -37.5689, sqrt(2)} is a possible answer.
Real, complex, quaternion, etc. But more specifically it's a transcendental real number, not being the root of an integer polynomial (and certainly not the ratio of two integers).
No. Pi is a set number, if it were negative (-3.14159...) it would not represent the ratio of radius to circumference.
